Step-by-step explanation:
Given: A lifeguard sees a person in distress.The eye level of the lifeguard is 15 feet above the ground. Angle of depression is 34°.
To find: Horizontal distance between lifeguard and the person.
Solution : If we draw a triangle then tan∅ =
Here base is the horizontal distance.
Now we put the values in the formula.
tan 34° =
Or Base =
=
So the answer is 22 feet.
